3 Overview

The distance measuring instrument is used to measure the distance and speed of the motor vehicle. Mainly by the measurement control unit, optoelectronics Speed sensor, display unit, mounting bracket composed of four parts, ranging from the structure of the tachometer shown in Figure 1. Fig.1 Schematic diagram of the structure of the distance measuring instrument Mounting bracket The photoelectric speed sensor is mounted on the vehicle and the light emitted by the sensor is irradiated to the ground. After the control unit is processed, the distance and speed of the motor vehicle are obtained.
